+# LLaVA-Phi Model
+
+This is a vision-language model based on Microsoft's Phi-1.5 architecture with CLIP for image processing capabilities.
+
+## Model Description
+
+- **Base Model**: Microsoft Phi-1.5
+- **Vision Encoder**: CLIP ViT-B/32
+- **Training**: QLoRA fine-tuning
+- **Dataset**: Instruct 150K
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, AutoProcessor
+import torch
+from PIL import Image
+
+# Load model and tokenizer
+model = AutoModelForCausalLM.from_pretrained("sagar007/Lava_phi")
+tokenizer = AutoTokenizer.from_pretrained("sagar007/Lava_phi")
+processor = AutoProcessor.from_pretrained("openai/clip-vit-base-patch32")
+
+# For text
+def generate_text(prompt):
+    inputs = tokenizer(f"human: {prompt}\ngpt:", return_tensors="pt")
+    outputs = model.generate(**inputs, max_new_tokens=128)
+    return tokenizer.decode(outputs[0], skip_special_tokens=True)
+
+# For images
+def process_image_and_prompt(image_path, prompt):
+    image = Image.open(image_path)
+    image_tensor = processor(images=image, return_tensors="pt").pixel_values
+    
+    inputs = tokenizer(f"human: <image>\n{prompt}\ngpt:", return_tensors="pt")
+    outputs = model.generate(
+        input_ids=inputs["input_ids"],
+        attention_mask=inputs["attention_mask"],
+        images=image_tensor,
+        max_new_tokens=128
+    )
+    return tokenizer.decode(outputs[0], skip_special_tokens=True)
+```
+
+## Training Details
+
+- Trained using QLoRA (Quantized Low-Rank Adaptation)
+- 4-bit quantization for efficiency
+- Gradient checkpointing enabled
+- Mixed precision training (bfloat16)
